Permission to write crossmod?

Would it be OK to write crossmod content with BGQE for an NPC mod I'm working on? Specifically, Ruak is a half-orc romanceable NPC and I'd like him to comment on the lovesick half-orc encounter, but I might write some other interjections if I think of them.

AmyAE: Of course, please go ahead! -Just on a side note: I am working on an update that introduces NPC reactions (for the original BG1 NPCs). So, in case you want your NPC to interject during the quests' dialogues it might be you'll have to update the code, too, depending on what I changed. But yes, any mod NPC reaction is welcome.
